Medium Size Telescopes
baseline for CTA includes 40 Medium-Size Telescopes (MSTs) – 25 in the southern
hemisphere and 15 in the northern hemisphere.
The MST will be built by an international
collaboration of institutes and universities from Germany, France, Brazil,
Poland, Switzerland and the United States. The MSTs
will be sensitive to gamma rays in the core energy range of CTA, from about 100
GeV to 10 TeV. The telescopes
have a modified Davies-Cotton design with a reflector of 12 m in diameter on a
polar mount and a focal length of 16 m. Based on the performance for shower
detection and reconstruction in this energy range for existing instruments, the
MSTs will use 10-15 m diameter optical reflectors made up of approximately 1.2
m mirrors and be spaced apart in the 100 m range.
